Error 1603 can't install AIR 3.2.0.2070 on Vista 32bit

Hi community.

I can't install Adobe AIR 3.2.0.2070. I'm getting the error:

"An error occurred while installing Adobe AIR. Installation may not be allowed by your administrator. Please contact your administrator."

1.     I'm the administrator of the computer.
2.     I'm running Windows Vista Home Premium 32-bit SP2.
3.     I've tried the right-click-run-as-administrator solution and I'm getting the same error.
4.     I've read Troubleshoot AIR installation | Windows and none of the solutions worked.
5.     I'm installing the latest AIR version (I've tried older versions too)

Here is my install log:

Sorry for my English, because my native languages are Spanish and Portuguese.

Hope someone can help. Thanks.
